Sorry for not noticing this earlier, but I should mention that although
I use some of the warnings infrastructure for reporting the
'duplicate-case-datum' and 'bad-case-datum' warnings, I never check for
those warning flags.  The warnings are reported unconditionally.

I had started to work on a patch set to make them conditional, but that
work was halted due to an unresolved disagreement about how warnings
should be specified.

  http://lists.gnu.org/archive/html/guile-devel/2012-02/msg00080.html

I felt, and continue to strongly feel, that we should not require the
user to provide a complete list of warning types that they want.  If we
do that, then users will be forced to hard-code that list into their
build systems (and/or code that uses 'compile').  If they do this, then
whenever we add a new warning type, no one will see the new warnings
until they modify their build system.

Can we revisit this issue?

   Regards,
     Mark
